Corannulene‐Based Quintuple 6/7Helicenes: Well‐Preserved Bowl Core, Inhibited Bowl Inversion and Supramolecular Assembly with Fullerenes

, indicating exceptional chiral stability. Surprisingly, the bowl inversions of Q6H-1 and Q6H-2 conformers are somewhat inhibited by the helical blades, whereas this was not observed for other possible conformers of Q6H. These results first demonstrated that subtle conformational variations can lead to significant changes in chiral stability and bowl inversions of multiple helicenes. Due to the well-preserved corannulene core, propeller-shaped conformation and electron complementarity, Q6H-2 can recognize fullerenes in both solution and solid state, which is a rare instance of co-crystallization assembly between multiple helicenes and fullerenes.
